KJ Leaf primordium 



KK Bud scale 



KL Leaf base forming a segment of a bulb (e. g. , a segment of an onion bulb). (For use with 



plants whose bulbs are formed of leaves whose upper parts are aerial. ) 



KM Leaf, in toto , forming a segment of a bulb (e. g. , a segment of a lily bulb). (For use with 



plants whose bulbs are formed of modified leaves [scales] that are totally subterranean 

 and which form aerial stems usually with typical aerial leaves. ) 



KN (To be used in Field H-1 only. ) Leaf other than the treated leaf and unspecified as to 



whether it is above or below the treated leaf. (The treated leaf, Symbol K, K4, or K5, 

 will always be coded in Field H-2 when Symbol KN is in Field H-1. ) 



KNl (To be used in Field H-1 only. ) Leaf below (older than) the site of local application of 



the test compound. (Code the plant part to which application is made [e. g. , internode, 

 node, leaf, or branch] in Field H-2 when Symbol KNl is in Field H- 1. ) 



KN2 (To be used in Field H-1 only. ) Leaf above (distal to and younger than) the site of local 



application of the test compound. (Code the plant part to which application is made [e. g. , 

 internode, node, leaf, or branch] in Field H-2 when Symbol KN2 is in Field H-1. )
